Crossing makes ink cartridge unit 14, black supply unit 15 and record head 8 be connected to each other and constitute.Here, showing about a kind of black color
The circulatory system, but the circulatory system is actually available for every kind of black color.
The main box 141 for storing the ink of relatively large capacity is arranged in ink cartridge unit 14.It is wrapped in black supply unit 15
Containing buffer pocket 151 and three pumps P0, P1 and P2 being connected to buffer pocket 151.Circulating pump P1 and P2 make in whole circulation route
Ink flow as follows, i.e., the ink in supply system from circulating pump P1 is passing through buffer pocket towards the direction of circulating pump P2
151 is mobile.
Liquid surface height sensor 154 is arranged in buffer pocket 151.Liquid surface height sensor 154 includes two pins, and
The position (height) of black liquid surface can be obtained by the existence or non-existence of the conduction electric current between two pins of detection.?
That is following situation can be detected using liquid surface height sensor 154: the black liquid surface in buffer pocket 151 reaches liquid
The height of face height sensor 154.Make-up pump P0 operation is thus from main box 141 when remained ink in buffer pocket 151 reduces

It is formed in each individual recording element substrate 80a with the independent flow path being connect with common recycling flow path 80c.Due at two
The appearance of pressure difference between vacuum cavitations unit is formed as follows black flowing in independent recording element substrate 80a,
That is, ink is flowed into from common supply flow path 80b with relatively high pressure, and ink flows out to common recycling with relatively low pressure
Flow path 80c.In addition, a part of recirculation ink disappears due to injection when carrying out spraying in recording element substrate 80a
Consumption, but remaining ink flows back into cycling element 81 by recycling flow path 80c jointly, and is back to buffer pocket by circulating pump P1
151。
In circular form ink supply system, the heat generated in the spraying in recording element substrate 80a is recycled
Ink ribbon walk.Therefore, even if in the case where being carried out continuously spraying, the injection occurred with thermal accumlation can also be inhibited
Failure.In addition, the construction of the bubble occurred due to spraying or the ink thickened, is less likely to leave foreign matter etc., therefore energy
Nozzle spray regime is kept in a satisfactory manner.
Particularly, with the characteristic that the bubble that spraying generates has upward side mobile.Therefore, when in injection discharge surface
When 8a (i.e. above-mentioned black injection unit 80) carries out record operation in the state of tilting as described above, there is also bubbles can remain in spy
The misgivings of fixed recording element substrate 80a or specific jet port.However, using circular form ink supply system,
The bubble by recycling flow path 80c generation jointly can be reliably recycled, therefore also increases the record head 8 in spraying
Posture freedom degree.As a result, the record position in Fig. 3 is also possible, therefore the size for being able to achieve device reduces.
However, preferably injection discharge surface 8a is configured to horizontal, so that the effect of gravity be made finally to make in maintenance position
For independent recording element substrate 80a and independent jet port.Therefore record head 8 needs position of readiness shown in Fig. 1, Fig. 3 institute
It is suitably moved between the record position and maintenance position shown in Fig. 7 shown, it is therefore desirable to which existing can be in the short time and with simple
Mode realize mobile construction.
